In the end, without replacing the motor, but the time ricciardo lost.
The Aussie qualified P6 on Saturday afternoon, with team mate Max Verstappen three places ahead following a session that perhaps did not reflect the progress Ricciardo feels was achieved.
The Red Bull driver has been under growing pressure this season following a number of key incidents, even suggesting he might "headbutt someone" on Thursday in response to ongoing questions about his performance.
It was at the 2007 Canadian Grand Prix that Hamilton won his first Formula One race, and he's since gone on to emerge victorious in five of the last eight trips to the Circuit Gilles Villeneuve in Montreal.
"We had a few problems".
Max Verstappen scored around the track in Montreal to record the quickest times in both practices ahead of the Canadian Grand Prix.
"I am not happy with sixth, but am I happy with the way I drove and actually what we did, yes".
However, this did not prevent Lewis Hamilton to lead the first part of practice, when riders worked on the harder tyre.
"I did it in '14", said Ricciardo, referring to his maiden F1 win in Canada when starting from the same position.
"It's a positive start to the weekend", the Dutchman said.
They were soon out to join the near-frenzied traffic, in which the Dutchman clocked a new record in 1:12.035, to go three-tenths clear of team-mate Ricciardo, who responded in record-breaking style. Especially Mercedes they're looking very quick there.
The young Dutchman clocked the best time of the day in the afternoon session, one minute, 12.198 seconds, ahead of Ferrari's Kimi Raikkonen and Red Bull team mate and Monaco Grand Prix victor Daniel Ricciardo.
"The others did a bit better but I'm not really bitter or anything at myself, I honestly did the best I could today".
But after the dreary spectacle in Monaco a fortnight ago, at least we can rely on one of the finest overtakers in the sport fighting his way back through the field to provide the entertainment this weekend. The vehicle has been working really well and we know in qualifying we are missing top speed. "Every single weekend you go in you try to win and here practice has been good".
The good news for Ricciardo is that Red Bull thinks he can get through the weekend without needing to use a new energy recovery system. The one from the failure in China is alive, hence we haven't got a penalty. So qualifying was good. Team-mate Sainz put the back end of his auto into the wall early in the afternoon and managed just nine laps.
Verstappen, who also spun out in Australia and finished sixth, said he's not going to change the approach that made him, at the age of 17, the youngest driver ever to compete in Formula One.
